$DAYJOB uses an immersion cooling system so it’s higher performance and much
quieter.

When buying a compute cluster, if there's a budget choice between
15 more teraflops, or 15 less decibels, the teraflops *always* win.

Because the cost differential to do so is a lot greater than the $10
to get some hearing protection?
Passive cooling typically translates to lower performance but also can
be more expensive.

I use Etymotic earplugs on my motorcycle as well as in other loud
environments, because they attenuate "without loss of clarity":

For me, it depends on the use case.

I am surprised some datacenters don't have a requirement for ear protection
when entering their facilitiy. Most large construction sites I have been to
required me to have ear plugs at least in a pocket and I have been

Obviously seek competent medical advice, but my understanding is that
this is a myth.
The energy of sound is what causes damage. Bach played at 120dB will do
